A GSS-API Mechanism for the Extensible Authentication Protocol
Abstract
This document defines protocols, procedures, and conventions to be
employed by peers implementing the Generic Security Service
Application Program Interface (GSS-API) when using the Extensible
Authentication Protocol mechanism. Through the GS2 family of
mechanisms defined in RFC 5801, these protocols also define how
Simple Authentication and Security Layer (SASL) applications use the
Extensible Authentication Protocol.
